Re: IMF strength

so hydrogen bonding trumps all covalent bonds, but ionic trumps all covalent bonds

No since that was taught after the sigma pi bond slides

Re: Hydrogen Bonding

Is there specific work that you would have to show for the dipole moments or just the arrows?

Re: CO2 and H20

Would the dipole moments cancel out?

Re: HCL vs NaCl

So all ionic compounds will have higher imf, boiling and freezing points than any covalent molecule, right?

Re: Hydrogen Bonding

and there would still be dipole moments and dispersion forces on the compound as well right?

Honestly besides doing well on the final, I just gotta hope that curve at the end is really generous for the overall grade.

But they will affect the shape, right? It's just that he will cover that in a later discussion right?
